Answer:
The correct answer is letter "B": an implied warranty of fitness for a particular purpose.
Step-by-step explanation:
An implied warranty is the grant a product or service has implying it will fit the purposes the product is being offered according to the use customers will give to the product. All goods being traded have an implied warrant unless the producer provides a disclaimer stating what factors of the product might not fit customers' purpose of use.
Thus, Rockridge is breaching the implied warranty of fitness term by selling spiked mountain-climbing shoes with spikes felling off while climbing on mountains.
